Cement fragment from hip arthroplasty causing deep femoral artery pseudoaneurysm

An 81-year-old woman who had undergone total hip arthroplasty 12 years earlier presented with a painful spontaneous hematoma in the proximal left thigh. A left hip radiograph showed a displaced cement fragment from the acetabular component of the hip prosthesis. Computed tomography confirmed an extruded cement fragment causing a large pseudoaneurysm of the deep femoral artery. The patient underwent successful percutaneous embolization of the pseudoaneurysm with coils.
